Hi. I wonder if someone can help me with a Pir security light problem I have. I fitted a new Pir light on the front of my garage the other day and found that the existing supply cable is a 4 core jobbie (brown, black, blue and yellow/green earth) and inside the new lamp there's just live neutral and earth connections. I tested the wires and found the brown wire was delivering 240v and the others nothing, so I clipped and taped the black wire and fitted the others. The light works perfectly - unfortunately there are 2 other auxiliary lights on the side and back of garage which were activated when the old Pir was triggered and these are no longer functioning at all. Where should the black wire go to remedy the problem? Any help would be gratefully received. Thanks guys.
